Came upon this cute photo of a Tawny Owl in one of the owl spam feeds, so no info or origin or anything.
Captive owls need mental stimulation like anyone else, so they are given objects they are unfamiliar with so they can explore them and interact with them.
RaptorTAG has a Google Doc with tons of enrichment ideas for raptors if you're curious.
Mmmmmm...nana...
